|Most people seem happy with their Tacktick instruments, but then most are only a couple of years old.
Bear in mind that most of these devices rely to some extent on a battery and that battery will have a finite life. My first Tacktick Racemaster died in three years; the current one stands at about five. Throwing out a $1500 wind system after five years is too painful to contemplate. As a point of contrast, a friend's B&G is over thirty years old and still going strong with one display head replaced.
So... balance the convenience of wireless with the cost. Can the battery be replaced by you or does it have to go back to the maker for a rebuild (which is 120 pounds UK for a Racemaster).

PS - This shouldn't be construed as a specific recommendation for Tacktick; rather, I'm using them as a way of saying that a) the first entrant has proved it's a viable and as far as I know, reliable, technology and b) there's a variable here - battery replacement) that doesn't seem to get a lot of awareness.
